Best Fruits for Weight Loss (Especially on GLP-1s)
Not all fruits are created equal when you're trying to lose weight. Here's exactly which ones to prioritize—and which to limit—especially on GLP-1 medications.
The Short Answer
The best fruits for weight loss are high in fiber, low in sugar, and high in water content. Think berries, citrus, and melon—not tropical fruits, dried fruits, or fruit juice.
Top picks:
- Berries (strawberries, raspberries, blackberries) - 5-7g sugar per cup, high fiber
- Watermelon - 9g sugar per cup, 92% water, very filling
- Grapefruit - 8g sugar per half, proven weight loss benefits
- Apples - 10g sugar per small apple, 4g fiber, high satiety
Why Fruit Choice Matters More on GLP-1 Medications
When you're on Ozempic, Wegovy, Mounjaro, or Zepbound, you're eating significantly fewer calories—often 1,200-1,500 per day. Every calorie needs to count toward nutrition and satiety.
The Problem with High-Sugar Fruits:
When you're eating limited food, high-sugar fruits can:
- Spike blood sugar and trigger hunger 1-2 hours later
- Use up calories without providing much satiety or protein
- Displace more nutrient-dense foods (like vegetables and protein)
- Cause digestive issues on an already-sensitive GLP-1 stomach
What to Look For in Weight Loss Fruits:
✓ High Fiber (3g+ per serving)
Fiber slows sugar absorption, increases satiety, and supports digestion—critical when you're eating less food overall.
✓ Low to Moderate Sugar (Under 15g per serving)
Keeps blood sugar stable and prevents post-fruit hunger crashes.
✓ High Water Content (80%+)
Adds volume and hydration without excess calories, helping you feel full.
✓ Easy to Digest
GLP-1s slow digestion, so you want fruits that won't cause bloating or discomfort.
Best Fruits for Weight Loss: Ranked
Here's our ranking based on sugar content, fiber, water content, satiety, and digestibility:
Best Choices - Eat Freely
1. Berries (Strawberries, Raspberries, Blackberries, Blueberries)
Per 1 cup serving: 50-85 calories, 5-9g sugar, 4-8g fiber
Why they're #1: Highest fiber-to-sugar ratio of any fruit. Berries are packed with antioxidants, low in calories, and extremely satiating. Raspberries have 8g fiber per cup—more than most vegetables.
Best for:
- Snacking between meals
- Adding to Greek yogurt or protein shakes
- Sweet cravings without blood sugar spikes
2. Watermelon
Per 1 cup serving: 46 calories, 9g sugar, 0.6g fiber
Why it's great: 92% water content makes it incredibly filling for very few calories. Despite lower fiber, the volume helps with satiety. Also helps with hydration on GLP-1s.
Pro tip: Eat a big bowl (2 cups) for under 100 calories when you want something sweet and filling.
3. Grapefruit
Per half grapefruit: 52 calories, 8g sugar, 2g fiber
Why it's great: Clinical studies show eating grapefruit before meals can enhance weight loss by 7-10%. Contains compounds that may improve insulin sensitivity. Very low calorie density.
Caution: Can interact with certain medications (statins, some blood pressure meds). Check with your doctor.
4. Cantaloupe
Per 1 cup serving: 54 calories, 13g sugar, 1.5g fiber
Why it's great: 90% water, high in vitamin C and potassium. Very sweet taste for relatively low sugar content. Easy on digestion.
Very Good - Eat 1-2 Servings Daily
5. Apples
Per small apple: 77 calories, 10g sugar, 4g fiber
Why they're good: High fiber (especially with skin on), very portable, extremely satiating. Studies show apples rank highest in satiety among common fruits.
6. Oranges
Per medium orange: 62 calories, 12g sugar, 3g fiber
Why they're good: High vitamin C, good fiber, hydrating. Eating whole oranges (not juice) provides satiety from fiber and pulp.
7. Pears
Per medium pear: 101 calories, 17g sugar, 6g fiber
Why they're good: Very high fiber (6g), excellent for digestion. Sugar is higher but offset by the fiber content.
8. Peaches
Per medium peach: 58 calories, 13g sugar, 2g fiber
Why they're good: Low calorie, sweet and satisfying, easy to digest. Good option when berries aren't in season.
Good in Moderation - Watch Portions
9. Bananas
Per medium banana: 105 calories, 14g sugar, 3g fiber
The issue: Higher in sugar and calories than most fruits. Can cause blood sugar spikes. However, good for pre-workout energy and potassium.
Pro tip: Choose smaller bananas (90 calories) or eat half at a time.
10. Grapes
Per 1 cup: 104 calories, 23g sugar, 1.4g fiber
The issue: Very high sugar, low fiber, easy to overeat (no natural "stop" point). One cup = 30 grapes, which you can eat in 2 minutes.
If you eat them: Pre-portion to 15-20 grapes (½ cup) and eat slowly.
11. Cherries
Per 1 cup: 87 calories, 17g sugar, 3g fiber
The issue: Moderate sugar, but very easy to overeat. Good antioxidants though, so enjoy in moderation.
Limit These - High Sugar, Low Satiety
12. Mangoes
Per 1 cup: 99 calories, 23g sugar, 3g fiber
Why limit: Very high sugar (almost as much as a candy bar). Doesn't provide enough satiety for the sugar load.
13. Pineapple
Per 1 cup: 82 calories, 16g sugar, 2.3g fiber
Why limit: High sugar, can be acidic and cause digestive discomfort on GLP-1s. Small portions only.
14. Dried Fruit (Raisins, Dates, Dried Cranberries)
Per ¼ cup raisins: 123 calories, 25g sugar, 2g fiber
Why avoid: Extremely calorie-dense and sugar-concentrated. Water removal means you can eat 400+ calories before feeling full. Dried fruit has 4-5x the calories of fresh fruit.
Exception: 1-2 dates as a natural sweetener in recipes, or 5-6 raisins on a salad for flavor.
15. Fruit Juice (Any Kind)
Per 8oz orange juice: 110 calories, 21g sugar, 0g fiber
Why avoid: All the sugar, none of the fiber or satiety. Drinking calories is the worst thing you can do for weight loss. Spikes blood sugar rapidly.
Better option: Eat the whole fruit instead. One orange = 62 calories with fiber. One cup orange juice = 110 calories with zero satiety.
How to Eat Fruit on GLP-1 Medications
Follow these guidelines to maximize the benefits of fruit while minimizing sugar impact:
✓ DO: Pair Fruit with Protein or Fat
This slows sugar absorption and increases satiety:
- Berries + Greek yogurt (20g protein)
- Apple slices + 2 tbsp almond butter
- Cantaloupe + cottage cheese
- Strawberries + mozzarella cheese stick
✓ DO: Eat Fruit Early in the Day
Your insulin sensitivity is highest in the morning, so your body handles fruit sugar better. Save protein-heavy meals for dinner when GLP-1 appetite suppression is strongest.
✓ DO: Prioritize Whole Fruits Over Smoothies
Blending breaks down fiber, making fruit sugar absorb faster. Chewing whole fruit increases satiety signals to your brain.
If you make smoothies: Add protein powder (20-30g), use frozen berries, include spinach or kale, and limit to 1 cup fruit max.
✓ DO: Keep Portions Reasonable
General rule: 1-2 servings of fruit per day (1 serving = 1 cup berries, 1 medium apple, ½ grapefruit). When you're eating 1,200-1,500 calories daily, 2 servings of fruit = 10-15% of your total intake.
✗ DON'T: Use Fruit as a Meal Replacement
Fruit alone doesn't provide enough protein or nutrients to count as a meal. Always pair with protein.
Bad: Eating an apple for lunch
Good: Apple + 2oz turkey + cheese stick (25g protein, balanced macros)
✓ DO: Buy Frozen Berries
Frozen berries are picked at peak ripeness and flash-frozen, preserving nutrients. They're cheaper, last longer, and perfect for adding to Greek yogurt or protein shakes. Just as nutritious as fresh.
Sample Day: How to Include Fruit on GLP-1s
Here's how to incorporate fruit into a balanced 1,400-calorie day on GLP-1 medications:
Breakfast (400 calories)
- 1 cup Greek yogurt (plain, non-fat) - 130 cal, 23g protein
- 1 cup mixed berries - 70 cal, 4g fiber
- 2 tbsp granola - 70 cal
- 1 tsp honey - 20 cal
- Coffee with almond milk - 110 cal
Lunch (450 calories)
- Grilled chicken salad - 350 cal, 35g protein
- Mixed greens, cherry tomatoes, cucumber, olive oil dressing
- Small apple on the side - 80 cal, 4g fiber
Snack (100 calories)
- String cheese - 80 cal, 8g protein
- ½ cup strawberries - 25 cal
Dinner (450 calories)
- 5oz salmon - 280 cal, 35g protein
- Roasted broccoli with garlic - 80 cal
- ½ cup quinoa - 90 cal
Total fruit: 1.5 servings (berries + apple + strawberries)
Total protein: 101g
Total calories: 1,400
Notice fruit is paired with protein at breakfast and lunch, not eaten alone. This maximizes satiety and minimizes blood sugar impact.

Frequently Asked Questions
Should I avoid fruit completely while trying to lose weight?
No! Fruit provides essential vitamins, minerals, fiber, and antioxidants. The key is choosing the right fruits (berries, melon, citrus) and eating appropriate portions (1-2 servings daily). Avoid fruit juice and dried fruit, which are sugar bombs without satiety.
Is fruit sugar the same as added sugar?
Chemically, fructose is fructose. However, fruit contains fiber, water, and nutrients that slow absorption and provide health benefits. A medium apple has 10g sugar but 4g fiber. A candy bar has 20g sugar and zero fiber. Your body processes them differently. That said, fruit sugar still counts toward your total carb/sugar intake.
Can I eat unlimited berries since they're low in sugar?
While berries are the best fruit choice, "unlimited" isn't realistic on a 1,200-1,500 calorie diet. Aim for 1-2 cups daily. Beyond that, you're using up calories that could go toward protein and vegetables, which are more critical for weight loss and muscle preservation.
Are frozen fruits as good as fresh?
Yes! Frozen fruits are flash-frozen at peak ripeness, preserving nutrients. They're often more nutritious than "fresh" fruits that have been sitting in stores for days. Frozen berries are perfect for smoothies, yogurt, or thawing as a snack. Just avoid varieties with added sugar.
What about fruit at night—will it prevent weight loss?
Timing matters less than total daily calories. However, eating fruit earlier in the day (breakfast/lunch) is better because: (1) insulin sensitivity is higher in the morning, and (2) you have all day to burn off the sugar. Save protein-heavy meals for dinner when GLP-1 appetite suppression peaks.
What if I'm craving a high-sugar fruit like mango or banana?
It's okay to have them occasionally in small portions (½ mango, ½ banana). Pair with protein (Greek yogurt, protein shake) to minimize blood sugar spike. Just don't make them daily staples—prioritize berries, melon, and citrus instead.
The Bottom Line
Fruit absolutely has a place in a weight loss diet—even on GLP-1 medications. The key is choosing high-fiber, low-sugar, high-water fruits and eating them in reasonable portions.
Your best choices:
- Berries (strawberries, raspberries, blackberries, blueberries)
- Watermelon and cantaloupe
- Grapefruit and oranges
- Apples and pears
Limit or avoid:
- Tropical fruits (mango, pineapple)
- Dried fruits (raisins, dates, dried cranberries)
- Fruit juice (all types)
- Large portions of grapes or bananas
Pair fruit with protein, eat it early in the day, and keep portions to 1-2 servings daily. This gives you the nutritional benefits without sabotaging your weight loss progress.
